2 Gudance Saemen on Calculaon Mehodology GIPS GUIDANCE STATEMENT ON CALCULATION METHODOLOGY Inroducon Achevng comparably among frms complan presenaons requres as much unformy as possble n he mehodology used o calculae porfolo and compose reurns. The unformy of he reurn calculaon mehodology s dependen on accurae and conssen npu daa a crcal componen o complance wh he GIPS sandards. Alhough he GIPS sandards allow flexbly n reurn calculaon he reurn mus be calculaed usng a mehodology ha ncorporaes he me-weghed rae of reurn concep for all porfolos excep for prvae equy. For nformaon on calculang performance for prvae equy see he prvae equy provsons and gudance. The GIPS sandards requre a me-weghed rae of reurn because removes he effecs of exernal cash flows whch are generally clen-drven. Therefore a me-weghed rae of reurn bes reflecs he frm s ably o manage he porfolos accordng o a specfed mandae objecve or sraegy and s he bass for he comparably of compose reurns among frms on a global bass. In hs Gudance Saemen he erm reurn s used raher han he more common erm performance o emphasze he dsncon beween reurn and rsk and o encourage he vew of performance as a combnaon of rsk and reurn. Rsk measures are valuable ools for assessng he ables of asse managers; however hs Gudance Saemen focuses only on he reurn calculaon. Money- or dollar-weghed reurns may add furher value n undersandng he mpac o he clen of he mng of exernal cash flows bu are less useful for reurn comparsons and are herefore no covered by hs Gudance Saemen. Gudng Prncples aluaon Prncples The followng are gudng prncples ha frms mus use when deermnng porfolo values as he bass for reurn calculaons: For perods begnnng on or afer January 20 porfolos mus be valued n accordance wh he defnon of far value and he GIPS aluaon Prncples n Chaper II of he GIPS sandards. For perods pror o January 20 porfolo valuaons mus be based on marke values (no cos bass or book values). Frms mus value porfolos n accordance wh he compose-specfc valuaon polcy. o For perods pror o January 200 porfolos mus be valued a leas quarerly. CFA Insue GIPS Gudance Saemen on Calculaon Mehodology

3 Gudance Saemen on Calculaon Mehodology o For perods begnnng on or afer January 200 porfolos mus be valued a leas monhly. o For perods begnnng on or afer January 200 frms mus value porfolos on he dae of all large cash flows. Frms mus defne large cash flow for each compose o deermne when porfolos n ha compose mus be valued. o Porfolos mus no be valued more frequenly han requred by he compose-specfc valuaon polcy. For perods begnnng on or afer January 200 frms mus value porfolos as of he calendar monh end or he las busness day of he monh. Frms mus use rade dae accounng for perods begnnng on or afer January [Noe: for purposes of he GIPS sandards rade dae accounng recognzes he asse or lably on he dae of he purchase or sale no on he selemen dae. Recognzng he asse or lably whn hree days of he dae he ransacon s enered no (rade dae T + T + 2 or T + 3) sasfes he rade dae accounng requremen for purposes of he GIPS sandards.] Accrual accounng mus be used for fxed-ncome secures and all oher nvesmens ha earn neres ncome. The value of fxed-ncome secures mus nclude accrued ncome. Accrual accounng should be used for dvdends (as of he ex-dvdend dae). Calculaon Prncples for Porfolos The followng are gudng prncples ha frms mus use when calculang porfolo reurns: All reurns mus be calculaed afer he deducon of he acual radng expenses ncurred durng he perod. Frms mus no use esmaed radng expenses. Toal reurns mus be used. Toal reurn s defned as he rae of he reurn ha ncludes he realzed and unrealzed gans and losses plus ncome for he measuremen perod. The calculaon mehod chosen mus represen reurns farly mus no be msleadng and mus be appled conssenly. Frms mus calculae me-weghed raes of reurn ha adjus for exernal cash flows. Exernal cash flow s defned as capal (cash or nvesmens) ha eners or exs a porfolo and s generally clen drven. Income earned on a porfolo s nvesmens s no consdered an exernal cash flow unless s pad ou of he porfolo. For perods begnnng on or afer January 2005 frms mus calculae porfolo reurns ha adjus for daly-weghed exernal cash flows. An example of hs mehodology s he Modfed Dez mehod. For perods begnnng on or afer January 200 a he laes frms mus calculae performance for nerm sub-perods beween all large cash flows and geomercally lnk performance o calculae perodc reurns. (Noe: For perods begnnng on or afer January 200 frms mus defne prospecvely on a compose-specfc bass wha consues a large cash flow.)

For perods begnnng on or afer January 200 frms mus calculae porfolo reurns a leas monhly. For perods pror o 200 porfolo reurns mus be calculaed a leas quarerly. Perodc and sub-perod reurns mus be geomercally lnked. Calculaon Prncples for Composes The followng are gudng prncples ha frms mus use when calculang compose reurns: Compose reurns mus be calculaed by asse-weghng he ndvdual porfolo reurns usng begnnng-of-perod values or a mehod ha reflecs boh begnnngof-perod values and exernal cash flows. The aggregae reurn mehod whch combnes all he compose asses and cash flows o calculae compose performance as f he compose were one porfolo s accepable as an asse-weghed approach. For perods begnnng on or afer January 2006 and pror o January 200 frms mus calculae compose reurns by asse-weghng he ndvdual porfolo reurns a leas quarerly. For perods begnnng on or afer January 200 compose reurns mus be calculaed by asse-weghng he ndvdual porfolo reurns a leas monhly. Perodc and sub-perod reurns mus be geomercally lnked. Cash Flow Prncples The followng are gudng prncples ha frms mus consder when defnng her compose-specfc cash flow polces: An exernal cash flow s a flow of capal (cash or nvesmens) ha eners or exs a porfolo whch s generally clen drven. When calculang approxmaed raes of reurn he calculaon mehodology requres an adjusmen for he dalyweghng of cash flows he formula reflecs a wegh for each exernal cash flow. The cash flow wegh s deermned by he amoun of me he cash flow s held n he porfolo. When calculang a more accurae me-weghed reurn a large cash flow mus be defned by each frm for each compose o deermne when he porfolos n ha compose are o be valued for performance calculaons. I s he level a whch he frm deermnes ha an exernal cash flow may dsor performance f he porfolo s no valued. Frms mus defne he amoun n erms of he value of he cash/asse flow or n erms of a percenage of he porfolo asses or he compose asses. The large cash flow deermnes when a porfolo s o be valued for performance calculaons. A large cash flow s dfferenaed from a sgnfcan cash flow whch occurs n suaons he frm deermnes ha a clen-dreced exernal cash flow may emporarly preven he frm from mplemenng he compose sraegy and he porfolo s emporarly removed from he compose or he exernal cash flow s placed n a emporary new accoun.

Approxmaon of Tme-Weghed Rae of Reurn As menoned n he nroducon he GIPS sandards requre frms o calculae a meweghed rae of reurn excep for prvae equy. The GIPS sandards allow flexbly n choosng he calculaon mehodology whch means ha frms may use alernave formulas provded he calculaon mehod chosen represens reurns farly s no msleadng and s appled conssenly. Calculang a me-weghed rae of reurn s no an easy ask and may be cos nensve. For hese reasons frms may use an approxmaon mehod o calculae he oal reurn of he ndvdual porfolos for he perods and sub-perods. The mos common approxmaon mehods combne specfc rae of reurn mehodologes (such as he orgnal Dez mehod he Modfed Dez mehod he orgnal IRR (nernal rae of reurn) mehod and he Modfed AI (ank Admnsraon Insue) mehod) for subperods and hen geomercally lnks he sub-perod reurns.
